And a former senior intelligence officer for a Western country who specialized in Russian counterintelligence tells Mother Jonesthat in recent months he provided the bureau with memos, based on his recent interactions with Russian sources, contending the Russian government has for years tried to co-opt and assist Trump—and that the FBI requested more information from him.

“This is something of huge significance, way above party politics,” the former intelligence officer says. “I think [Trump’s] own party should be aware of this stuff as well.”

Does this mean the FBI is investigating whether Russian intelligence has attempted to develop a secret relationship with Trump or cultivate him as an asset? Was the former intelligence officer and his material deemed credible or not? An FBI spokeswoman says, “Normally, we don’t talk about whether we are investigating anything.” But a senior US government official not involved in this case but familiar with the former spy tells Mother Jones that he has been a credible source with a proven record of providing reliable, sensitive, and important information to the US government.
